Malacosoma pini Schaeffer 1906: 248

Diagnosis. The black head, unicolorous elytra, and appendiculate claws distinguish this species from others of the genus Triarius   . Males of T. pini   have dark elytra ( Fig. 2a View Fig ); females have pale elytra ( Fig. 2b View Fig ). Specimens measure 5.0–8.0 mm in length.

Type Material Examined. We studied the male holotype, female allotype, two male paratypes, and two female paratypes ( USNM).

Type Locality. “ Carr’ s Peak, Huachuca Mts. , Arizona (9000 ft).”  

Geographic Distribution. We examined specimens from Cochise County in Arizona and the Municipio de Durango in the Mexican state of Durango. Presumably, the species also occurs in one or more of the Mexican states between Arizona and Durango, but we have not seen specimens. Beyond this, Wilcox (1965) stated that this species occurs in Texas, but this may have been in error. We are not aware of any specimens from Texas.

Temporal Distribution. We examined adults collected in June and July.

Plant Association. This species is reported from pine ( Pinus   L., Pinaceae   ) ( Schaeffer 1906; Wilcox 1965; Clark et al. 2004).

Comments. In addition to the type material mentioned above, we also examined 30 other specimens.
